摘要
Abstract
Based on the trip fault of Tianshcnqiao-Jinzhou 500 kV transmission line, this paper analysed the accident tower design parameters and geographical characteristics, calculated the lightning resisting level and checked the windage yaw angle, then found that the trip-out accident caused mainly by windage yaw flashover. It is suggested that it should take the preventive measures of adding on the insulator string of one insulator, and changing the L form league board to the carrying-on form league board, also hanging heavy hammers. These preventive measures can improve line insulation level, also have certain effect to guard against lightning failures.关键词
